I just pulled the trigger on a small Schiek 3004 powerlifting belt. I am working my way up through a back injury, but I hit ~65% of my 1RM the other day and had it on for shits and giggles. I really liked the way it felt, and I think it will work well for me.

I am going from a 6" to the 4.5", and while I thought I would miss the extra width, it is stiff enough to provide support.

Jesus, that is a terrible sounding sentence were you to take it out of context.
